Abstract
Lattice strain engineering represents a cutting-edge approach capable of delivering enhanced performance across various applications. The lattice strain can affect the performance of electrochemical catalysts by changing the binding energy between the surface-active sites and intermediates. In this work, lattice strain is regulated through a homo/heterogeneous atomic interface merging. The strong lattice strain and electronic interactions between Ni and Mo facilitated the reaction kinetic of HER. The prepared NiMo@SSM exhibits excellent HER catalytic performance with 70 mV overpotential at the current density of 10 mA cm-2 and long-term stability. The method of controlling lattice strain through hetero/homo atom interface merging provides a new strategy for designing high-performance alkaline HER electrocatalysts.
晶格应变工程是一种能够提高各种应用性能的尖端方法。晶格应变可通过改变表面活性位点与中间产物之间的结合能来影响电化学催化剂的性能。在这项工作中，晶格应变是通过同质/异质原子界面合并来调节的。镍和钼之间的强晶格应变和电子相互作用促进了 HER 的反应动力学。制备的 NiMo/SSM 具有优异的 HER 催化性能，在电流密度为 10 mA cm-2 时过电位为 70 mV，并具有长期稳定性。通过杂原子/母原子界面合并控制晶格应变的方法为设计高性能碱性 HER 电催化剂提供了一种新策略。
期刊介绍：
ChemPlusChem is a peer-reviewed, general chemistry journal that brings readers the very best in multidisciplinary research centering on chemistry. It is published on behalf of Chemistry Europe, an association of 16 European chemical societies.
Fully comprehensive in its scope, ChemPlusChem publishes articles covering new results from at least two different aspects (subfields) of chemistry or one of chemistry and one of another scientific discipline (one chemistry topic plus another one, hence the title ChemPlusChem). All suitable submissions undergo balanced peer review by experts in the field to ensure the highest quality, originality, relevance, significance, and validity.
